Implementation Reference
- src/index.ts:463-473 (handler)The handler function that implements the logic for the 'get_performance_metrics' tool. Currently, it returns a message indicating that JWT authentication is required for full access.
private async getPerformanceMetrics(args: any) { // Performance metrics require JWT authentication return { content: [ { type: "text", text: "Performance metrics are not available via API key authentication. JWT authentication is required for this feature.", }, ], }; } - src/index.ts:225-252 (registration)Registration of the 'get_performance_metrics' tool in the listTools response, including name, description, and input schema definition.
